Abstract

DGAT1, AGL and protoncogen c-myc genes have been mapped on chromosome 4 and considered as candidate genes for carcass quality traits. The aim of the study was to characterize the polymorphism of these genes in four groups of pigs and to evaluated the relationship between the DGAT1, AGL and c-myc genotype and carcass traits. The animals of cross-breed PLW x PL were used only to characterize these polymorphisms. All animals studied appeared to be polymorphic at these loci. Statistical analysis was carried out for each breed separately using the least square methods of the GLM procedure. The relationship between the polymorphism and several productive traits was identified in each of the study group of pigs. Animals carrying heterozygous genotype at this locus showed most extreme values for some of the traits tested. Our results suggest that these genotypes might be utilized in the selection of valuable pig carcass traits.
